How did vaccines come about?
In order to understand this, we need to talk about smallpox. Small pox holds a unique place in medicine as it was one of the deadliest diseases known to humans, and, to date, is the only human disease to have been eradicated by vaccination. Smallpox would cause body aches, high fevers, sore throat, headache and even difficulty breathing. The worst part was a pus-filled rash that would cover the whole body. Smallpox was a devastating disease, about 3 out of every 10 people which contracted it, died.
Watch my video to find out more about how smallpox paved the way for conventional vaccinations:
Conventional vaccines include: live viruses that have been attenuated (weakened or altered so as not to cause illness); inactivated or killed organisms or viruses; inactivated toxins (for bacterial diseases where toxins generated by the bacteria, and not the bacteria themselves, cause illness); or merely segments of the pathogen (this includes both subunit and conjugate vaccines).
mRNA vaccines utilize mRNA which codes for a specific protein. Once this mRNA is injected into an individual, the cells will take it up and make the protein. This protein is then displayed to the immune system and an immune response is activated against the protein.
*My video above describes in detail the different types of conventional vaccines and how they differ from mRNA vaccines.
